u/erica/JeansInstability
v11 v12 105 105 for finite [[latex($\lambda_J$)]] (i.e. pressure gradients are null/gravity dominates), the characteristic collapse time becomes 106 106 107 [[latex($\tau = [\frac{1}{4 \pi G \rho0}]^{1/2} ~ \frac{1}{2} t_ ff$)]]107 [[latex($\tau = [\frac{1}{4 \pi G \rho0}]^{1/2} ~ \frac{1}{2} t_{ff}$)]] 108 108 109 109 where [[latex($t_ff$)]] is the freefall time for a spherical region of uniform gas.
